Just recently I was looking into making bets on polymarket - a prediction market that uses Ethereum and advertises zero fees. I happened to have a bit of eth from a while back but I was dismayed to find out that the transfer fee, seemingly to move any amount of eth into polymarket, was something like a flat 50 dollar equivalent. I just wanted to bet with a few hundred dollars, and having to spend 50 of that just to get started felt unfun.
